I have used it. Still feel like crying every time I think of what it cost me. I had two different groups of calves that were coughing and at least 10% of each group were having more severe symptoms of pneumonia. It cleared them up and so far I haven't lost anything that I gave it to, even though some of them looked like they should die. I have one that I didn't catch in time and he probably won't recover. So far I am pretty impressed, it isn't quite as dramatic as micotil but I also don't have to worry about killing myself with it.

Dean, when you guys get alot of coughing etc and some sickies, have you ever put sulphamethazine in the water? I do that when getting lots of coughs, etc and you would be surprised how fast that ill clear them up and they look better, do it for about 3 days in a water tank, it helps alot.
